最佳答案
您似乎没有从 \extras\google\google_play_services\libproject\google-play-services_lib 导入项目。
将它作为 library 添加到您当前的项目中。
确保您已为 11 以下的 API 使用 SupportMapFragment。
?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
